The sensors are typically connected in a Wheatstone bridge configuration and mounted on the surface or body to be tested. Semiconductor sensors, for example crystalline silicon, can provide good strain sensitivity with significantly reduced sensor area and also reduced bridge power compared to metal resistor bridges. a-Si:H strain sensors fabricated on glass substrates have recently been demonstrated (G. de Cesare et al, Thin Solid Films, vol. 427, p. 191, 2003).

This work presents a new room-temperature zero-bias rectifier that significantly simplifies detector design, mitigates current induced flicker and burst noise, and eliminates bias circuitry and related noise, leading to an inexpensive square-law detector with noise floor /spl sim/10/sup -12/ W/Hz/sup 1/2./ Our devices are all epitaxial MBE grown rectifier diodes consisting of an ErAs semimetal film grown in-situ on Si-doped InAlGaAs on InP substrates. The small lattice mismatch (2.1 %) in this material system allows the ErAs to be grown as a dislocation-free single crystal for sufficiently thin layers over semiconductor epi-layers. The contact is thermodynamically stable, robust, and eliminates the possibility of oxide formation at the Schottky interface.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"106 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133623989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several passive matrix OLED displays fabricated on polymeric substrates have been demonstrated. For high information content displays, active-matrix pixel addressing provides improved display performance and reduced power consumption. To date, all active matrix OLED displays have been fabricated on rigid substrates and most used polysilicon thin film transistors (TFTs) as the active elements because they can provide sufficient current at low voltages and acceptable device dimensions. However, improvements in the efficiency of OLEDs allows lower mobility TFTs, such as those based on hydrogenated amorphous silicon (a-Si:H) or even organic semiconductors, to be used as OLED drive devices (M.A. Baldo et al, Appl. Phys. Lett., vol. 75, pp. 4-6, 1999). The lower processing temperatures of a-Si:H and organic TFTs may permit the use of polymeric substrates. In this work, 1 mm/sup 2/ a-Si:H TFT phosphorescent OLED active matrix pixels and pixel arrays were fabricated on 50 /spl mu/m thick polyimide substrates.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115773204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These structures result in high series resistance and parasitic capacitance. A source/drain-on-insulator (SDOI) structure with elevated source/drain combined with an oxide isolation, formed by a shallow trench process underneath the source/drain region, is reported to be a potential solution to simultaneously reduce the series resistance and parasitic capacitance. However, the optimization of SDOI structures is very tricky and the tradeoff between series resistance and gate-to-drain Miller capacitance is not obvious. In this paper, the advantage of this MOSFET source/drain engineered structure is verified by detailed device simulation with extremely scaled MOSFETs. Device structure parameter optimizations are discussed to maximize the intrinsic performance. Design guidelines and potential performance gain with the SDOI structure are also discussed.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"125 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116577246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has allowed the engineering of the differential resistance of the access regions in these transistors, allowing a significant improvement of their DC and RF characteristics. In the future, the combination of multiple channels separated by different barrier heights will increase even more the linearity of the AlGaN/GaN HEMTs.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126250235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process was successfully integrated into a traditional CMOS flow and the electrical and reliability results of HfON, as compared to HfO/sub 2/, showed 10 times less Vt shift in the pulsed Id-Vg measurement and up to 70% gate leakage reduction. In addition, EOT, electron/hole mobility, TDDB and subthreshold slope of HfON also performed better than those of HfO/sub 2/.
